i want load image dynamically in report. name of image comes database , in expression i'm creating repo path.

"repo:/images/"+$f{image_name}

but gives me error if image not in repository.. when image not in repository want load default image instead of error.

i tried not working.

new java.io.file("repo:/images"+$f{image_name}).exists()?"repo:/images"+$f{image_name}:"repo:/images/default_image"
